Class nucmass_mnmsk (o2scl)¶

class nucmass_mnmsk : public o2scl::nucmass_table ¶

Nuclear masses from Moller, et al.

This is based on the tables given in [Moller95], [Moller97], and [Moller16ng].

In order to allow easier coordination of file I/O across multiple MPI tasks the constructor does not automatically load nuclear mass data. To load data from the HDF5 data files, use o2scl_hdf::mnmsk_load(). If no data is loaded, then o2scl::nucmass_table::is_loaded() will return false and calls to get_ZN() will call the error handler.

There are several entries in the original table which are blank because they are in some way not known, measured, or computable. These entries are filled with a positive number larger than 1.0e90, given by the functions blank(), neither(), beta_stable(), beta_plus_and_minus(), greater_100(), or very_large() .

Note

This class requires data stored in an HDF file and thus requires HDF support for normal usage.

Public Functions

nucmass_mnmsk()¶

virtual ~nucmass_mnmsk()¶

virtual bool is_included(int Z, int N)¶: Return false if the mass formula does not include specified nucleus.

virtual double mass_excess(int Z, int N)¶: Given Z and N, return the mass excess in MeV.

nucmass_mnmsk::entry get_ZN(int l_Z, int l_N)¶

Get the entry for the specified proton and neutron number.

This method searches the table using a cached binary search algorithm. It is assumed that the table is sorted first by proton number and then by neutron number.

inline double blank()¶: The value which corresponds to a blank entry.

inline double neither()¶: Neither beta+ or beta- is possible.

inline double beta_stable()¶: The value which corresponds to a blank entry.

inline double beta_plus_and_minus()¶: Both beta+ and beta- are possible.

inline double greater_100()¶: The value is greater than 100.

inline double very_large()¶: The value is greater than \( 10^{20} \).

inline virtual const char *type()¶: Return the type, "nucmass_mnmsk".

int set_data(int n_mass, nucmass_mnmsk::entry *m, std::string ref)¶

Set data.

This function is used by the HDF I/O routines.

Protected Attributes

std::string reference¶: The reference for the original data.

nucmass_mnmsk::entry *mass¶: The array containing the mass data of length ame::n.

int last¶: The last table index for caching.
