• The Joshi effect ±Δi has been studied in oxygen, in the visible, as a function of the applied potential V under electrodeless 'sleeve' excitation. The positive effect +Δi sets in well below the breakdown 'threshold potential' V_m, increases with V to a maximum at a limiting potential T_i near V_m, and decreases thereafter; it changes sign (to the negative effect -Δi) at an inversion potential V_i. Above V_i, -Δi increases with V. The initial increase in +Δi is the consequence of enhanced photoelectron emission due to diminution, under fields F, in the surface work- function φ in proportion to √<F>. The subsequent diminution in +Δi and inversion are due to simultaneous occurrence of -Δi which sets in near V_m and increases rapidly with V.
