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 either 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

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

int last¶: The last table index for caching.
