epraya.Cristalfm#

Cristalfm(Hamer, Exp)#

Function for the calculation of the spectrum of monocristals without producing the graphs.

Parameters:

  • Hamer (Class) – Container for the hamiltonian parameters of the system.

  • Exp (Class) – Container for the experimental conditions.

Returns:

  • espac1 (np.array) – Array of the magnetic field.

  • inten1 (np.array) – Array of the counts of the spectrum.

  • Elist (np.array) – Array of the energy values of the hamiltonian

  • dfdis (pandas.Dataframe) – Table of the kets and transitions of the system.

Example

>>> import epraya as epr
>>> Ham,Exp,_=epr.Start()
>>> Ham.S=1
>>> Ham.I=1/2
>>> Ham.g=np.array([2.003, 2, 2])
>>> Ham.A=np.array([200, 200, 200])
>>> Ham.Hpp=[0, 20]
>>> Exp.Freq=9.4
>>> Exp.Points=4096
>>> Exp.Temperature=300
>>> Exp.Frange=[0,800]
>>> print(epr.Cristalfm(Ham,Exp))
