Selecting bands

On selecting Data, Select Band(s) in level scheme mode, the band selection panel shown on the right is displayed.

The bands in the current data sets will be displayed in the list. The user can select any band or bands by clicking on entries in the list. When the OK button is selected, a level scheme in the band mode will be displayed.

In the band mode, the bands are displayed separately from each other:

The order of the bands is determined by optimizing the out of band transitions. When there is feeding between non-adjacent bands, the level fed is extended horizontally with a gray line. Levels from non-selected bands which are fed from selected bands, are shown as horizontal gray lines of the full width of the display.

At present levels and gammas can not be selected in band mode, but the properties of the gammas (gamma-ray energy, initial/final level energy and spin-parity, relative intensity and multipolarity) is displayed in the status bar at the bottom of the screen when the mouse is on top of a gamma.

Selecting levels

On selecting Data, Select Levels in level scheme mode, the level selection panel is displayed:

The panel contains a number of filters that can be applied to the selection of levels:

Yrast: Selects yrast levels (the level of highest spin at a certain excitation energy)
Parity: Selects levels with odd, even parity or no parity assigned. More than one option may be selected
Spin: Selects levels with even and odd spin and on a range of spin values
Energy: Selects levels within a range of excitation energies
Half-life: Selects levels within a range of half-lives
