Description	The experimental study of collisional processes pertinent to formation and destruction of astrophysically relevant ions is the main aim of the proposed project. It is proposed to study participation of ions H3+and D3+ (and partly also H2D+ and D2H+) in these processes. The research will be concentrated on recombination of H3+ ions in vibrational groundstate and in lowest rotational state (J=1, K=1) and in the next lowest state (J=1, K=0), para-H3+ and ortho-H3+, respectively. The goal of the study is to rationalize role of rotational excitation of H3+ ions in low temperature hydrogen containing plasma at conditions relevant to astrophysics. It is proposed to study ion-molecule reactions leading to formation of para-H3+ and ortho-H3+, respectively. The rate coefficients of recombination of para and ortho-H3+ with electrons will be measured using Stationary afterglow (SA) and Flowing afterglow (FALP) techniques adapted for measurements at low plasma temperatures and equipped with near infrared laser absorption spectroscopy (NIR-CRDS configuration) (en) Hlavním cílem projektu je experimentální studium procesů tvorby a zániku astrofyzikálně důležitých iontů. Je navrhováno studium procesů, ve kterých se zúčastňují ionty H3+ a D3+ (a částečně též studium iontů H2D+ a D2H+). Výzkum bude zaměřen na rekombinaci iontů H3+ v základním vibračním stavu a nejnižším rotačním stavu (J=1, K=1) a též v dalším vyšším rotačním stavu (J=1, K=0); stavy označované jako para-H3+ a ortho-H3+. Cílem studia je ozřejmění role rotační excitace iontů H3+ ve vodíkovém plazmatu v podmínkách relevantních pro astrofyziku. Navrhováno je i studium reakcí vedoucích k tvorbě iontů para-H3+ a ortho-H3+. Rychlostní konstanty rekombinace budou měřeny na aparaturách “Stationary afterglow” (SA - stacionární dohasínající plazma) a “Flowing afterglow” (FALP - proudící dohasínající plazma) upravenými pro dané měření a doplněnými o laserovou absorpční spektroskopii v blízké infračervené oblasti (v konfiguraci NIR-CRDS).
