Absorption lines
Absorption lines cut down from the continuum as sample thickness climbs the absorbance gauge beside them, then ease back.

Nuclide
15 animationsActivity read-out
Counts arrive at random intervals and scroll past the counter window while the rate bar beneath settles around the mean activity.
CSSAlpha decay
A two-proton two-neutron cluster leaves the parent nucleus along its trajectory and the nucleus recoils as the alpha particle clears.
CSSBeta decay
A neutron in the core converts to a proton and the beta particle it releases runs out along the trajectory line.
CSSCross-section resonance
A probe sweeps the energy axis and reads the neutron cross-section off the curve above it, topping out on the resonance peak and resting there.
CSSDecay chain
Activity steps from parent to daughter to the stable end of a decay chain, the final nuclide ringing once as it arrives and keeping it.
CSSElectron shell filling
Closed inner shells hold while the valence shell fills around the nucleus, an electron riding the leading edge of the occupied arc.
CSSElectron transition
An electron is pumped from the ground rule up an energy level diagram, holds in the excited state, then drops back and a photon leaves the atom.
CSSEmission spectrum
A cursor scans the wavelength axis and each emission line lights as it is crossed, the reference spectrum holding faint underneath.
CSSFusion
Two light nuclei close along the approach rail onto the target crosshair, merge into a single product and release energy on the four axes.
CSSGamma emission
An excited nucleus tightens as it de-excites and a gamma packet runs out along the propagation axis and clears the frame.
CSSHalf-life
Remaining activity halves once per half-life, the column stepping down the time axis while its head tracks the decay curve.
CSSInduced fission
A slow neutron reaches a heavy nucleus, the core swells and splits into two fragments driven apart, and two prompt neutrons leave on the diagonals.
CSSIsotope series
A cursor walks one element's isotope row across the nuclide chart a neutron at a time and settles on the cell lying on the band of stability.
CSSOrbital lobes
A pair of p-orbital lobes swells away from the nucleus and relaxes back while the nodal plane and the second orbital hold as construction.
