Constructor & Destructor Documentation

AlphaSpectrum() [1/6]

AlphaSpectrum::AlphaSpectrum	(	double	Emin,
		double	Emax,
		int	NumberOfBins,
		bool	log = false
	)

Standard Constructor of a AlphaSpectrum.

Parameters

Emin	: Lower Energy bound of the Spectrum
Emax	: Upper Energy bound of the Spectrum
NumberOfBins	: Number of bins
log	: true if logaritmic binning is wanted (default=false)

This constructor creates the Energy binnig automatically. The binning is constant for linear bins and with constant log step for log bins

AlphaSpectrum() [2/6]

AlphaSpectrum::AlphaSpectrum

(

vector< double >

LowerEnergy

)

User input bining Constructor of a AlphaSpectrum.

Parameters

LowerEnergy

: Lower energy bounds of each bin vector + upper energy bound of the last bin.

Usefull for non constant binning. Energy range of bin number i is :fLowerEnergy[i] <= Energy < fLowerEnergy[i+1]

AlphaSpectrum() [3/6]

AlphaSpectrum::AlphaSpectrum	(	double *	LowerEnergy,
		int	NumberOfBins
	)

User input bining Constructor of a AlphaSpectrum.

Parameters

LowerEnergy	: Lower energy bounds of each bin array + upper energy bound of the last bin.
NumberOfBins	: Number of Lower energy bounds of each bin (the LowerEnergy array dim is thus NumberOfBins+1

Usefull for non constant binning. Energy range of bin number i is :fLowerEnergy[i] <= Energy < fLowerEnergy[i+1]

AlphaSpectrum() [4/6]

AlphaSpectrum::AlphaSpectrum

(

string

BinningFileName

)

File User input bining Constructor of a AlphaSpectrum.

Parameters

BinningFileName

: The binning file name containing the lower eenrgy bounds of bins.

Usefull for non constant binning. The file must start with N, the number of bins. Then, follow the lower bounds of each bins (N real values) and then the upper bound of the last energy bin (the (N+1) value). Thus the file must contains N+2 line for N lower bin bounds.

AlphaSpectrum() [5/6]

AlphaSpectrum::AlphaSpectrum	(	int	NumberOfBins,
		double	a,
		double	b,
		double	c
	)

Constructor of a Spectrum with binning build with this calibration law : E(Lowerbin)=a*Lowerbin*Lowerbin + b*Lowerbin + c.

Parameters

NumberOfBins	: Number of Lower energy bounds of each bin (the LowerEnergy array dim is thus NumberOfBins+1
a	: first coefficient of the calibration law (eV)
b	: second coefficient of the calibration law (eV)
c	: third coefficient of the calibration law (eV)

Usefull for experimental spectra

AlphaSpectrum() [6/6]

AlphaSpectrum::AlphaSpectrum

(

const AlphaSpectrum &

spect

)

Copy constructor.

Read ENSDF Data and fill the Alpha Spectrum.

Member Function Documentation

ExtractDataFromLine()

void AlphaSpectrum::ExtractDataFromLine ( string  Line, Material *  TheParent, double  NAtoms  )

ReadENSDF()

AlphaSpectrum * AlphaSpectrum::ReadENSDF	(	int	Z,
		int	A,
		int	I,
		double	NAtoms = 1
	)

Parameters

Z	: Z of the mother nucleus
A	: A of the mother nucleus
I	: isomeric state of the mother nucleus
NAtoms	: the number of atoms of the mother nucleus
